ICE-SCORING MACHINE.

Application filed January 3, l1929. Serial No. 330,049.

This invention relates to machines forscoring ice; and the object is to provide a simple machine which will be economical as compared with other ice scoring machines. The advantage of this invention is that the machine can be manufactured at relatively small cost. Another advantage is -that blocks of ice may be scored vertically and horizontally in a single Ycontinuous move` ment through the machine and there may be as many scores made both vertically and horizontally as may be desired for preparing different sizes of blocks of ice. Another advantage is in the simplicity in the operation of the machine and the saving in timel of scoring the ice blocks. Other objects and advantages will be fully lexplained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form apart of this application.

This machine is provided with any suitable frame having upright members in pairs 1 and 2 and inclined members 3. ALower longitudinal beams 4- are connected to the members 1, 2, and 3. U per longitudinal beams 5 are attached to the upper ends of the members 1, 2, and 3. The members 4 are simply the upturned fianges of the platform 6. Al platform 7 is attached to the beams 5 and supports the operating mechanism. An endless conveyor 8 is mounted on wheels 9 and 10, the latter being an idler provided with a shaft 11. The shaft 11 is journaled in bearings 12 which are attached to the beams 5. The wheel 9 is provided with a shaft 13 which is journaled in bearings 14 which are attached to the beams 5.

The shaft 13 is driven by gearing from a motor 15 which is mounted on platform7.

The motor. 15 is provided with a shaft 16 and a worm gear wheel 17 is rigid with the shaft 16 and drives a worm gear wheel 18 which is rigid with a shaft 19. A wormA gear wheel 20l is rigid with shaft 19 and drives a worm gear wheel 21 which is rigid with shaft 22. A bevel gear 23 is rigid with shaft 22 and drives la bevel gear wheel 24 which is rigid with shaft 13 which drives the gear wheel 9 for drivin the conveyor 8. The conveyor 8 is provided with impellers 25 and 26 for moving the blocks of ice through the machine.

Provision is made` for scoring the blocks of ice horizontally. Saws 27 are rigid with vertical shafts 28. The shafts are driven from the shaft 19 by means of gear wheels e 29 which are rigid with shaft 19and lmesh with wheels 30 which are rigid .with shafts 28.

The vertical scoring .is accomplished by i traveling saws 31. The saws 31 are rigidshaft 34 is provided with an endless groove 35. A lug 36 is rigid with the bearing37.

Theshafts 34 revolve in bearings 37 whichare moved by `the lugs 36 which project into the grooves in the shafts 34.. The bearings 37 are prevented fgom revolving withthe shafts 34. A guide 38 is provided for each shaft 34. Each bearing 37 is provided with a projecting guiding arm 39 which has a bearing for engaging the guide 38. The arm 3 9 simply slides on the guide 38 and so prevents the bearings 33 and 37 vfrom revolving withy the shaft 34. The guide 38 carries bearings 40 and 41 for the shaft 34,

both bearings rigid with the guide 38.

Each bearingv 41 ha's,a projecting bearing 'I arm 42 which carries a bearing 43 for a driv- Y ing Shaft 44. The shaft 44 telescopes 'in the shaft 45. A worm wheel 46 is rigid with shaft 44 and drives wworm gear wheel 47 which is rigid" with the shaft 34. The bearing 37 and bearing 33 travel between the bearings 40 and 41.v The shaft 45 is driven lfrom theshaft 22 by means of a gear Wheel 48 which is rigidpwith shaft 22 and a gear wheel 49 which is rigid with shaft 45. As l each saw 31 moves downwardly and upwardly it is continuously driven by a iexible shaft 50. Each shaft 50 is vfixedly connected with a saw shaft 32 andthe other end of'the shaft 50 is driven by a. shaft 51'to -which the shaft is fxedly'connectedl The shaft 51 is driven from shaft 16 by means of a gear wheel 52 which 1s rrgrd with shaft 16 and a gear 53 which -is rlgld with the shaft 51.' E, v.

The shaft 34' and its guide 38 and'saw 3 1 with their gearing an cooperating ,parts constitute a unit for vertical scoring "and each side' of the machine is provided with 'such vertical scorin unit. See Fig. 2.

" Means are provi ed for laterally shifting v each vertical scoring unit so that the saws may be moved out of the vpat-h of the blocks ofoice when the saws are being moved back to starting position. By such .provisiom the An oscillating shaft 56 bearings 57 onthe upper and lower frame members 5 and 6 respectively. The shaft 56 is provided with arms 58 which have slots alo in their ends and lugs 59 are rigid with the arms 54 and project into the-slots in' the arms 58. The shaft 56 is parallel to the guide 38 4and shaft 34. `The shaft 56 has an arm 60 rigid therewith and the arm is provided with a slot in theend thereof. The

arm 60 engages a lu`g61 which is, rigid with a shifting member' 62 which is slidably mounted in guides 63 which are mounted on the upper frame members 5. Levers 64 are fulcrumed on the platform 7 and have slots in their work ends to receive lugs 65 which are rigid with the shifting member 62. The

operated ends of the levers 64 project into the path of the impellerscarried by the endless conveyor 8. When. the lugs or impellers 25 and 26 lengage the levers64, the levers are actuated to move the shifting member 62 for oscillating the shaft 56 which will v l bring the saws 31 into scoring position. The

saws 31 are held in' scoringposition byv an off-center trip 66 which is pivotally mounted on""a bracket 67. The trip is held against movement -by a spring 68. 'Ifhe tri holds ,an arm e9 which is' rigid with the s aa 5c.

l`In the drawings, Fig. 4, 'the full line shows the parts olit of scoring position. The dotted outline shows the parts in scoring position. The depth of scoring may be controlled by a set screw 70 whichcan varv the distancel of'travel of the trip 66. The spring 68 holds the saws 31'either in or out of scoring position. ,i

The scoring units'A are automatically shifted laterally at the end of a scoring operation. The bearings .37 strike spring arms 54' steel shifting devices 71. The scoring units `shafts 34. When the saws reach their upper limit, the are automatically shifted to scoring positions. VThe impellers 25 and 26 are so timed as tost-rike one of the levers 64 when the scoring units are to be shlfted laterally towards the sides of the machine'to bring the scoring units-in scoring positions.

The arrow heads in Fig. 1 show the dlrecdrawings show one score 72 Aalready made and another score 73- partly completed.l In this machine the saws' 31 are set vertically and the driving and guidin devices for imoving thesaws upwardly an downwardly are set at inclines and the amount of inclina-y -tion must be timed with the speed of movetion of the movement of the ice blocks. a The vment of the blocks of ice in order that the scoringde'vices may have the proper motion to score the ice vertically as'the blocks move horizontally through the machine. The levers 64 and the impellers 25 and 26 may be adjusted to score the blocks of ice as many times as maybe desired, for-making ice blocks of different Weights.

' Instead of the flexible shafts for driving the saws, anair motor may be used for this purpose and the operation will otherwise be the same. A wind-wheel 74 is mounted in the housing 37 and a hose 75 is provided for furnishing air for driving the wind-wheel. .It is apparent that various chan es in the slzes, proportions, construction, an arrangement of the several parts may be made without departing from my invention.

More scorlng units may be provided on each side of the machine if required.
